TODAY • Get out you ESRT and a piece of paper • The following questions are from your ESRT. • You’ll have a minute per question…
Question 1 • What is the difference between weathering and erosion?
Question 2 • How do glaciers move?
Question 3 • What is a turn a river called?
Question 4 • How can we increase likelihood of a mass movement.
Answers • What is the difference between weathering and erosion? • Weathering breaks down and erosion moves. • How do glaciers move? • Gravity • What is a turn a river called? • Meander • How can we increase likelihood of a mass movement. • Water, people, Slope, mass, vegetation
Vocabulary • Mass movement • Slump • Slide • Fall • Flow • Scarp • Vegetation
Mass wasting • This is when the earth (soil/dirt) begins to move down hill • GRAVITY it driving force.
Mass movements • Slump • This is when the land slides down equally. • Slide • This is when the land slides down not equally. • Fall- avalanche • The land falls • Flow • The land is liquefied and flows down.
Things that will increase mass movements • Change water content • Change slope • Change mass • Change vegetation • Change human activity
Which type of mass movement was this? • Slide, Fall, Slump, Fall??? • They called it the Tully Landslide. Was it a slide? • What caused this to happen?

Tully Landslide • April 30, 1993. After a long winter full of rain and snow. The saturated land gave away and began to flow down the hill.
